Thank You for Your response.
I have already installed last version 1.17.2 and I applied the patch.
Autosave in composer editor was repaired.
But sometimes I have trouble with lost of data in filled request form after submitting. I think that this trouble is caused by session issue.
If I understand this patch right it can repair session issue.
The bug there was also before this patch and I thought that the patch also repair this issue with data lost in filled form. I think that is much better but sometimes when I submitting form I lost filled data.
Is there another tip to solve this trouble?
Thank You very much.
Best regards, Ales
